Last Update:Feb 23 2022 4:45pm • Est. Read Time:Est. Read Time: 2 MIN

What is the KRACK?

In short, an attacker within range of a person logged onto a wireless network could use key reinstallation attacks (KRACK) to bypass WPA2 network security and read information that was previously assumed to be securely encrypted — thereby enabling them to steal sensitive data passing over the network, be it passwords, credit card numbers, chat messages, emails, photos, etc.

Is my Rachio affected? 

All messages between Rachio products and our servers are encrypted to ensure all user data is secure and not visible to attackers. Our security team is investigating the KRACK vulnerability and will release any updates needed to address the issue. We recommend our users follow guidelines released by the WiFi Alliance and ensure their network equipment is running on the latest software available.

UPDATE: 10/18/17; 9:30a MST

Our Wi-Fi vendors have identified patches for Generation 1 and Generation 2 controllers. The patch will be automatically applied once available; no updates by the user are required. 

What can I do to protect myself?

As noted above, we recommend our users follow guidelines released by the WiFi Alliance and ensure their network equipment is running on the latest software available. So you should update all your routers and Wi-Fi devices (laptops, phones, tablets, etc.) with the latest security patches.
